Estes Skylab #001973, Build, Part 24, The Detailed Wrap

I saved the most detailed wrap for last, figuring I would have had enough practice to tackle it.

After the vertical quarter section border lines were drawn, I shaded the black areas lightly with a pencil. It's easy to confuse which areas are which.

Here's the pencil marks at the upper band, 9/16" tall. 

The high points of each rib corrugation are measured and marked.

I used the promotional plastic quote card again as a shorter straightedge.

Where the line areas get shorter you can cut up shorter lengths of the card.
